What Is Korean Black Bean Powder?
Korean black bean powder — known in Korea as konggaru (콩가루) — is a roasted soybean powder made by toasting whole seoritae black beans and milling them into a fine, nutty flour, used for coating rice cakes, baking, and dusting desserts.
It's the black bean powder Korean kitchens have used for generations — the coating on injeolmi, the dust on bingsu, the nutty swirl in a latte. If you've heard it called bokkeun konggaru — "roasted bean powder" — that's this.
Black Bean Powder vs. Kinako
Kinako is Japan's roasted soybean flour; konggaru is Korea's. Made the same way — whole soybeans, roasted, then milled — so they're interchangeable. This one is the black soybean kinako of Korea: 100% seoritae instead of yellow soybeans, for a deeper, roastier flavor.
Point 1
100% Seoritae Black Beans
One ingredient, nothing else. Whole Korean-grown seoritae — black skin, green heart — selected and cleaned at the mill in Seongju. Full contents: 100% black soybeans.
Point 2
Roasted Low and Slow, Then Micro-Milled
Whole beans are roasted at low temperature in-house, then micro-milled into a fine, smooth roasted soybean powder. Slow roasting keeps the nutty aroma deep and the color even.
Nutritional Value
35g of protein per 100g — the beans do the heavy lifting. No added salt, no added sugar: the 7g of sugars is the bean's own.
Values from the product nutrition label, per 100g (3.5 oz). Egg comparison ≈6g protein per large egg, for reference only.
How to Use It
Injeolmi & rice cakes
The classic coating for injeolmi; works on any mochi or rice cake where you'd use kinako.
Injeolmi bingsu & toast
Dust it over shaved ice, or layer with honey between toasted milk bread.
Baking
Swap about ¼ of the wheat flour in cookies and pound cakes; reduce liquids slightly.
Lattes & smoothies
1–2 tablespoons into milk, oat milk, or a banana smoothie.
Yogurt & ice cream
A nutty finishing dust.
Porridge & overnight oats
Stir in for a roasted base note.

Yes, one-to-one. Anywhere a recipe calls for kinako, this works — with a deeper roasted flavor.

Roasted. Whole seoritae beans, low temperature, in-house, then micro-milled.

35g per 100g, per the nutrition label.
